-3 Claims. (01. 214-400) H shown in the accompanying drawings, but it is to be'expressly understood that such drawings are for the-purpose of-illustration only, andare not designed to define the limits of the invention,- reference-being had to'the appended claims for this purpose. In said drawingsg Fig. 1 is a" perspective view of one form which ,the invention may assume, with the container shown inelevated position;

Fig. 2 is a side elevationwith the container in 20 a position slightly below its elevated or top position; and v Fig. 31s antend elevation of Fig. 1.

In: said drawings, in3 which like reference numerals indicate like parts throughout" the several 2-1 views,- l-l are sideframe bars of the chassis of "a truck, and,2- -2 indicate base bars suitably secured to the frame bars I by any suitable means as by clamps 3-3. These 'basebars'are suit- I ably spaced 'by spacing elements 4 provided withm) downwardly extending brackets 5, by means of which they are bolted to the base bars 2. By providing space bars 4' of varying lengths, base bars 2 may besuitably spaced to conform to the spacingof frame bars l-l of different vehicles. 3., An upwardly extending tracker way, preferably slightly inclined, is provided with rails 6 which,"if desired, may be provided with anti-friction rollers -l3'---6'. The rails 66 are secured at their lower ends to the rear ends of the base bars 4n 22'by means ofa'rod 1 extending across and through the rails and base bars, the rails being spaced from the base bars 2 by means of sectional tubing 8 extending between the inner face of each rail and the outer face of each base bar with 4- a clamping nut 1' (Fig.1) holding each rail into intimate contact with the sectional'tubing.

9--9 are brace bars, thelower ends of which are suitably secured, as by bolts, to the base bars 2--2, the upper ends of which brace bars extend an to a point between the rails 22, as clearly shown in Figs. 1 and 3. A shaft I (Fig. 3) extends from 'side to side of the structure with its ends projecting outside of the rails 66 of the track or way and turns in bearings on the rails of the track or .55 way and on the upper ends of the brace bars will be more fully explained hereafter.

' 9-9. As here shown, said bearingsare formed in the rails of the track or wayand in the brace bars, said shaft extending through the rails of the track or way and through the brace bars. A truss rod ll extends across the extreme upper end of the rails 6- 6 with its outer ends deflected downward where saidends are engaged by collars -I2-l2 on the shaft 10. Mounted onthe outer ends of the shaft [0 and fixed thereto are .two

drums I 3"l3 whichdrums are spaced from the 10 rails 6-6 by the collars I2--l2.. These drums being fixed to the shaft l0, revolve therewith, as Fixed on the shaft i0 between the rai1s 6--6 isa third drum'll having a cable I5 wound thereonand with one end fixed thereto, the 'other' end of the cable l5 being connected to a suitabIepow'er device here shown as a cylinder l6,rnounted between the bars 99,-and as here shown connected to one of said rails by suitable supports,

I and preferably having thelower end thereof supported -on one of the cross bars 4. As here shown this cylinder has substantially the same'angle of inclination as the brace bars 9, and the piston rod I6 thereof is connected to the end -of the cable Ill. The piston i6" (Fig. 2) is actuated by any suitable fluid under pressure which, if desired, may be supplied by the engine of the truck. This fluid pressure is directedto one or the other side of the piston l6 by means of a valve I! (Fig. 2), controlled by a line or rod l1 extending to the driver's seat. As the specific construction of this power device forms no part of the present invention, it need not be described further than to say that any power device capable of applying power to the cable I! may be employed.

Mounted to turn on theshaft Ill is. any suitable catch 18 in position-to engage a part of the container to hold the same in elevated position during transportation by engaging a suitable part 4.0 of the container, as for example, a bail I9 rigidly secured to the back wall of the container. This swinging catch I8 is provided with means, as an adjusting screw l8, engaginga rod 20 extending across between the rails 66, to the end that the catch may be held in suitable position to be engaged by the bail I9 as the container reaches its elevated position. The specific construction of the'catch and its means of adjustment form no 60 part of the present invention and,need not be I further described. This catch I8 is spaced from the drum M by suitable tubular section 21 on the shaft l0 and spaced from one of the brace bars 9 by a similar tubular section 2| on said shaft i0. Likewise, the brace bars are spaced from the rails M by tubular sections 2|".

Wound on. the drums it-li and with one end secured thereto are cables 22-22, the free ends of which are; provided with suitable means as hooks 12' for engaging lugs on the ends of the container 2I.. which container as here shown is of the bottomdump'variety but it is to be expressly understood that the invention is not limited to any particular form of container or any particularmethod of dumping the same, the

containerhere shown being merely used for the nurpoaeof m 1-1.: i j- In-Joperation'when the container -is-"on' the on the ends'iof the container, and the shaft in 7 is revolved bymoving the piston in the cylinder ll inward. The revolution of the shaft It serves to revolve the drums l3-ll and wind up cables g 21-22 thereon, thus elevating the container to aposition where it is engaged by the catch I8, which position is the one it occupies porting from point to point.-. j

, It will be observed that by reason of the abilin trans- 3 ity to adjust the base bars 2-2 to any desired width and fix the same by means of the space bars 4, such bars can be spaced so as to conform to the spacing between the bars i-i of the truck, and by'suitable spacing of the upper ends so of the brace bars 9 byineans of the tubular Having thus described the invention, what is claimed is:

1. In a transporting and dumping vehicle, the combination of an upwardly extending track or way, a shaft extending across the upper portion of said track or way and with its ends projecting out beyond the said track or way, drums keyed to the projecting ends of said shaft, 8. container movable up and down on said track or way, flexible connections passing around said drums and engaging said container. brace bars engaging said shaft, means spacing the ends of said-brace barsalong said shaft. base bars secured to the section 2l',--;2i' they' may be suitably spaced.

from the rails Furthermore. by reason of the-fsctthat' the shaft it asses through the railsfi-ft andbrace bars 9-4, no riveting or 35 bolting is required to enable the brace bars to effectively perform their function. Furthermore, by removing the drums l3i3 and releasing the drum it and the shaft ID. the same may be withdrawny'pthus permitting the railst-B to. be

, .49 turned downward ba mel with the base bars z -'-2 I and the brace bars 9 can also be placed in a line with the base bars 2 by simply removing the bolts securing the lower ends thereof to said base a 'bars." This permits the entire structure other I than thejcontainer to be placed in Compact P the base bars a haft passing through the u er "sition for shipment. It will be seen that the entire structure consists of a minimum number "of parts readily assembled by unskilledlabor,

5 and is one of great strength and effective operation.
